Batch Controller Hazardous Area

The ProtEX+ loop-powered explosion-proof & intrinsically safe flow rate/totalizers can be installed virtually anywhere to provide convenient and informative display of any 4-20 mA signal. They can operate down to -40°C and be installed in areas that get as cold as -55°C, however the display will cease functioning. One of the most convenient features is the dual-line display, typically used to display the flow rate on the 5-character alphanumeric top display and flow total, flow grand total, or tag on the 8-character alphanumeric bottom display. The top display uses 12-segment, and the bottom display uses 14-segment alphanumeric characters for clear indication of tags, units, or alarm messages. Further enhancing the display on these instruments is a 20-segment bargraph.

The ProtEX+ carries all major approvals including:

•  UL Listed as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
•  CSA Certified as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
•  ATEX and IECEx Certified as Intrinsically Safe / Explosion-Proof

Four CapTouch through-glass buttons are available to operate the instrument without removing the cover. Free, PC-based, MeterView XL software that connects to the meter via a micro USB cable is available for programming and setup of the meters.

All models come equipped with two open collector outputs and a digital input. There are also models available with two solid-state relays and isolated 4-20 mA analog output options. The relays can be programmed for alarm indication, sample, timer, batch control, or stopwatch.

The PD6938 ProtEX+ pulse input flow rate/totalizers can be installed in a variety of areas (hazardous, dirty, wet, corrosive, hot, or cold) to provide convenient and informative display of flow rate and total from any pulse output flowmeter. These instruments will accept a variety of pulse inputs, including slow pulse rates. They can be powered from a 9-30 VDC power supply or the 4-20 mA output loop, have on-board datalogging capabilities, come with explosion-proof and intrinsically safe approvals, and can be ordered with optional 4-20 mA output and two relays. The PD6938, with the addition of its two optional relays, can also be used as a simple batch controller.

The ProtEX+ carries all major approvals including:

•  UL Listed as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
•  CSA Certified as Explosion-Proof / Dust Ignition-Proof / Flame-Proof
•  ATEX and IECEx Certified as Intrinsically Safe / Explosion-Proof

The PD6938 can operate down to -40°C and is certified by the agencies to be installed in areas that get as cold as -55°C.

The PD6938 ProtEX+ is available in aluminum and stainless steel enclosures that are designed for easy use and installation. The process connection is available in M20, 3/4" NPT and 1" NPT and there are two other conduit holes for field wiring.

Free, PC-based, MeterView XL software that connects to the meter via a micro-USB cable is available for programming and setup of the instruments. Four CapTouch through-window buttons are available to operate the instrument without removing the cover.

All models come equipped with two open collector outputs and a digital input. There are also models available with Modbus RTU RS-485 communications, two solid-state relays, and isolated 4-20 mA analog output options.

The ProtEX-MAX PD8-6210 offers all the functionality of the ProVu PD6210 as a CSA, ATEX, and IECEx certified explosion-proof product. It is available in an aluminum or stainless steel enclosure and will operate over a wide temperature range of -55 to 65°C (-67 to 149°F). It is an analog input (4-20 mA, 0-5 V, 1-5 V, etc.) digital batch controller specifically designed for single and multi-stage batching applications. It provides excellent but simple batch control capabilities with features such as preclose relays and automatic overrun correction for more accurate batches and convenient CapTouch through-glass buttons for simple operation and menu navigation without having to remove the cover. The preclose deactivates a specific relay before the batch is finished in order to allow slower fill rates and increased accuracy. Automatic overrun correction keeps the batch size accurate over time and with system wear. The PD8-6210 includes a 24 VDC power supply to drive the flowmeter and can be equipped with four internal relays and a 4-20 mA analog output.

The ProtEX-MAX PD8-6310 offers all the functionality of the ProVu PD6310 as a CSA, ATEX, and IECEx certified explosion-proof product. It is available in an aluminum or stainless steel enclosure and will operate over a wide temperature range of -55 to 65°C (-67 to 149°F). It is a pulse input (NPN, PNP, TTL, switch contact, sine wave, etc.) digital batch controller specifically designed for single and multi-stage batching applications. It provides excellent but simple batch control capabilities with features such as preclose relays and automatic overrun correction for more accurate batches and convenient CapTouch through-glass buttons for simple operation and menu navigation without having to remove the cover.
